BOTTLE-sToPPER.

SPECIFICATION forming part of Letters Patent No. 418,706, dated January*7, 1890. Application filed October 30, 1889. `Serial No. 328,624. (Nomodel.)

To .all whom' t may concern:

Be it known that I, JOIN A. EDES, a citizen of the United States,residing at Lawrence,

`in the county of Essex and State of Massachusetts, have inventedcertain new and useful Improvements in Bottle-Stoppers, of`

which the following is a full, clear, and exact specification.

The invention relates to the class of laterally-expansible Stoppers forbottles, cans, and jars; andthe object is to provide a stopper of thisclass which is cheap, few in parts, easily operated to tightly seal orunseal the mouthof the vessel into which it is inserted, safe againstaccidental removal, and sol constructed that no metallic or corrosivesubstance comes in contact with the contenta of the vessel sealed. y

In the accompanying drawings, where the invention is illustrated, Figurel is a side view of the neck of a bottle sealed by my improved stopper.Fig. 2 is a View of the same in central verticalsection. Fig. 3 is aplan view. K

In the views, the letter a denotes the neck of a glass bottle in themouth of which one of my improved Stoppers is inserted. This stopperconsists of a tapered core b, usually formed of metal, which ispreferably threadedV from end toend of the tapered portion and providedat the smaller end witha handle or thumb and finger piece c. .The body dof the` stopper is formed of any expansible and somewhat elastic material-as rubber-which vis suitable for eorking a bottle, and thisbody, which is cylindrical, is molded, cast, or otherwise placed aboutthe core b. A head e may, if desired, be formed on the upper end of thebody to prevent the stopper from being driven too far into the mouth ofthe bottle is inserted in the mouth of the bottle, can, or

jar which it is intended to seal and the handle rotated alittle, so thatthe screw is slightly drawn from the body, which, as the taperingthreads move upward into the body of the Stopper, where there is morematerial and a smaller opening for the screw, causes the body to expandlaterally or radially of the 'threads and tightly fill and seal themouth of p ward the stopper is readily pulled out by the handle, shouldthe-sides stick or adhere to the bottle, as the larger end of the coreis at the inner end of the stopper and of course cannot be pulled out ofthe body of the stopper. sion of the body is overcome byfso turning thehandle of the core that it is screwed farther out of the body, so thatthe larger end of the core is brought up to where there is more materialin the body. and the life of the stopper is much longer than priorStoppers on account of this fact.

I claim as my inventionl. A bottle-stopper consisting of an eXpansiblebody and a threaded tapering core having a handle at the smaller end,substantially as specified.

2. A bottle-stopper consisting of an expansible body provided with ahead to prevent too far insertion into a bottle, and a threaded taperingcore incased within the body and having a handle attached to the smallerend, whereby the core may be rotated ,substan tially as specified.
